Application fied June 10, 1908. Serial No. 437,705.

`Machinery, of which the 'following is a specitica-tion.

Our invention relates to new and nnproved feeding devices for woodworking ma? chinery, and is shown applied to a so-called outside molding machine i-ii which there is a stock-su porting table adjustable on the outside of tiie ina-in frame, the feed-rolls being mounted above said table, although our/.fimprovements may, in whole or in part, be' employed in other relations.

Our invention consists in providing a supplemental frame for the gearing which drives the u )per feed-rolls, means being provided for a justing the supplemental frame longitudinally of the main. frame and thereby changing the transverse relation between the bearings of the cross-shafts for saidfeed-rolls g further in mounting said bearings so as to swing for acconunodating the diiierent angles crosswi-se of the machine into which said drive-shafts may be shifted by the shifting of said supplemental frame; further in providing novel means whereby the feed-rolls may be quickly brought into operative or in'- operative position, it being understood that said devices are ap )licable where a single feedroll and where a p urality of feed-rolls is eniployed; and further, in the parts, and in the construction, arrangement, and combinations of parts hereinafter more fully described and claimed.

In the drawings: Figure -1 is a plan view of our improved device shown i-n connection with so much of an outside molding machine as is necessary to illustrate our invention. Fig. 2 is a front elevation of the same. Fig. 3 is a rear elevation of the saine, the lower part of the main frame being brokenaway. Fig. 4 is a. vertical cross-section of the same on the line x-:c of Fig. 1. Fig. 5 is a detail in section on the line y-y of Fig; 2, showing the mount-ing of the gear-housing for driving the lower feed-rolls. Fig. 6 is a perspective view of the supplemental frame. Fig. 7 is a vertical section on the -line z-z of Fig. 1 showing the pressure'nieans for the upper feed-roll and the means for quickly bringing the same into operative and inoperative positions; and, Fig. Sis a detail in rear elevationY showing the upper end of the latter.

1 represents the main frame on which a stock-supporting table 2 is adjustable vertically in guide-ways, one of which is shown at 3f," in any suitable or usual manner.

4 represents a cutter-head shown as an upper cutter-head, and if desired, further cutter-heads for cutting the lower face and the side edges of the stock may also be provided in usual manner, that part of the machine in which these cutter-heads are usually mounted not being shown, as the saine forms no part of our present invention.

5 is a supplement al frame which is mounted and adjustable on the main frame. We have shown this mounting accomplished by providing the main frame with a guide-wt 6 on which the supplemental frame is slida le` on a slideway7 of a flange 8, the supplemental frame preferably also comprising an apron 9 which slides against the side guide-way 10 of the mainframe. Set-screws 11 l2 are threaded in lugs 13 14 on the main frame and engage lugs 15 16 on the supplemental frame. The manipulation of these set-screws will force the su pplemental frame lengthwise on the guide-ways of the main frame. For securing the sup ple-ment al frame iii adj usted positions y JOHN ii. THOMAS .iin JOHN J. Mareas, or CINCINNATI, oiiio, .-issioxoiis To JQ i. mv e we provide bolts 1T which pass through slots 1S in the supplemental frame and are threaded into the main frame.

The supplemental frame preferably comprises a yoke 21 which extends laterally trom the apron 9, the driving gearing for the upper feed-rolls 22 '23 being preferably with iii the yoke and so arranged as to move with the supplemental frame in its adjustments. Thus 24 is a drive-shaft jouriia-led in bearings 25 26 in the supplemental frame, the bearing 25 being shown iii the yoke and the bearing 26m the side plate or apron. This driveshaft may be driven b v a suitable pulley 27.

2S is a master gear mounted on an intermediate drive-shaft '29 and engaged by a pinion 30 on the drive-shaft 24. The shaft 29 is jouriialed iii bearings 31 32, the bearing 31 being shown on the yoke andthe bearing 32 on the apron of the supplemental frame. 'The shaft 29 also carries a pinion .33 which meshes ith the gears 34 35 mounted respectively on the cross-shafts 36 37. These cross-shafts are respectively journaled in bearingsSS 39 and 40 11, these bearings 38 39 and 40 41 being preterably mounted so.

as to )ermit of4 their swiveling movement. Thus t 1e bearings 3S 40 are pivoted on the supplemental frame adjacent the gear ends of said shafts, andthe bearings 39 41 are pivot-ed on the main frame adjacent the roll ends of said shafts. lVe accomplish this pivoting )referably by providing these respective earings with a downwardly projecting shank 42 journaled in a socket 43, these sockets 43 at the gear ends of said shafts being on the supplemental frame and at the roll ends of said shafts being on the main frame. These-bearings are ireferably provided with slots 44 through wliich bolts 45 pass respectively `into the supplemental frame and the main frame for clamping the bearings rigidly in place after the supplemental frame has been adjusted for settingl the feed-rolls at an angle crosswise of the table for giving the stock a lead or tendencyto press against the side gage 46, this side gage being shown formed by the side face of the main frame. The angle or lead required is different for ditlerent classes of stock or different classes of work, and our improved device permits this adjustment to be made by shitting the respective feed-rolls simultaneously from dillerent points while maintaining the cross-shafts parallel. The crossshaft 36 also has a gear 47 secured thereto which meshes with a gear 4S on a roll-shaft 49. The cross-shaft 37 has a. gear .30 secured thereto which meshes with a gear 51 secured to the roll-shaft 52. The roll-shaftI 49 is journaled in bearings 53 in a housing 54 pivoted about the shaft 36 as on bearings The roll-shaft 52 is journaled in' bearings 50 of a housing 57 pivoted about the cross-sha1' t 37 as by bearings 5S. These roll-shaf ts resiectively carry suitable feeding-rolls as siown at 22 23. These rolls are adjustable toward or from the stock passing over the bed as by means of set-screws (i0 adjustable in lugs 01 02 of the respective housings and ada )ted to rest on the main frame.

*or driving the lower feed-rolls there is a gear 65 mounted on a shaft Gti'journaled in bearings 67 GS respectively on a lug 69 of the yoke and on the apron. The gear 05 is meshed by the gear 50 and in turn meshes with a gear 70 on a cross-shaft. 71 journaled in a bearing 72 of the supplemental frame at its ower receiving end and in a bearing 73 vin tie main frame at its power transmitting end. 74 is a gear-housing. It has a bearing 75 onan annular stud 7G, thereY being a gear 77 inside said housing on said cross-shaft 7 l There may be loose tit of this cross-shaft 71 at its power-transmitting end.

78 is a gear meshing with the gear 77 and is on a sha-ft 79 journaled in bearings S0 of said gear-housing.

81 82 are the lower rolls.- Lower roll S1 is on a shaft S3 jou'rnaled in bearing-blocks 84 S5 adjustable in guide-Ways S6 S7 in the which meshes with the gear 7S' and with whichA it is maintained in mesh by a link 91 Aconnecting the swinging end of the gearf housing with the roll-shaft.

92 is an intermediate gear on a shaft 93 journa-led. in the table andA meshes with the gear on the lower roll-shaft- 83. I`he` lower' feed-roll S2 is on a shaft 9-1 journaled in bearing-blocks 9:3 96 adjustable in slideways 97 9S of the table by means of setscrews 99 100. and meshes with the intermediate gear 92.

It is desirable that the'feed-rolls be pressed `toward the stock which passes over the lower feed-rolls and table. We accomplish this preferably by spring pressure means. Thus is a spring 'shown as a spiral spring received about a rod 106 having a. cup 107 adjacent its lower end in which the lower end ofthe spring is received, the upper end ot the spring being received i Aa socket 1 0S in a forwardly extending branch 109 of abraeket 110. The rod'is articulated with the rollerhousing as by means abolt 111 passing through an eye 1.12 of thelfrdand lugs 1 13 on said housing. lhe rod 106 preferably a. threaded rod. A nut 1 14 isadjustable at the lower end of said rod for th "j'iiirpose of positioning the cup 107 and the "e adjust-ing the tension ot'` the spring.

115 116 are inclined mating `fac`e\s\` about said rod, preferably spiral, one of"said `faces being on said bracket and the other of said faces being on a turn-bloeit 117 received about said rod and having 'a handle lSfor turning the same. A-nut or nuts 119 are adjustable. on the. upper end of the rod, so thatv` when the handle is turned, the turn-block may contact one of said nuts and raise thel rod and feed-roll with said turn-block. These nuts may also be. employed for adjustably limiting the descent of said feed-roll- When the handle is turned it causes the inclined-face 116 to slide upon the inclinedface and thereby raises the turn-block 117, forcing the rod 100 upwardly with it. for quickly raising the feed-roll out of contact with the work passing thereunder for instantly stopping the feed, this construct-ion forming a ver)T convenient, quickly acting and lstrong mechanism for instantly bringing the feed-roll into operative or inoperative positions.

F or limiting the turning of the turn-block in one direction for permitting descent of the feed-roll, the bracket and turn-block are respectively provided withabutting-faces 120 121, and toA limiting the turning of the turnblock in the other direction for preventing overthrow of said inclined faces, the bracket and turn-block are respectively providedv with lugs 122 123,. the lug 123 contacting the A gear 101 is on the shaft 94 inv raised positions.

lug 122 when the turn-block has been turned to its limit for raising the feed-roll housing and the feed-roll therein. When in this latter position, the highest points on the respective inclines rest on' the comparatively fiat faces 125 126 respectively on the bracket and turn-block for permitting the rolls to remain Each of the feed-rolls is preferably provided with the raising means just described. The brackets or uprights 110 preferably extend from the respective bearings 39 41 of the cross-shafts 36 37.
